To all whom it may concern:

Be it known that I, WVILLIAM B. GEORGE, a citizen of the United States, residing at Tulia, in the county of Swisher and State of Texas, have invented certain new and useful Improvements in Drain Cocks, of which the following is a specification.

This invention relates to a drain cock, designed primarily for use in connection with the radiators of motor vehicles, but it is to be understood that a drain cock in accordance with this invention can be employed for any purposes wherein it is found applicable, and the invention has for its object to provide, in a manner as hereinafter set forth, a drain cock capable of being operated from the instrument board of the vehicle for draining a radiator when occasion so requires, as well as capable of being operated below the radiator and independent of the operating means from the instrument board of the vehicle for the purpose of draining the radiator.

A further object of the invention is to provide, in a manner as hereinafter set forth, a drain cock including a resilient controlling element and a valvular element and with the resilient controlling element connected with the valvular element and employed for not only maintaining the valvular elementin closed position but further for maintaining it in open position when occasion so requires.

A further object of the invention is to provide, in a manner as hereinafter set forth, a drain cock including a barrel and a valvular element for closing the same, and further setting up the valvular element with respect to the barrel to prevent the freezing up of a water drain passage formed in the barrel, under such conditions providing a drain cock which can be used for drainage purposes irrespective of the temperature of the weather.

A further object of the invention is to provide, in a manner as hereinafter set forth, a drain cock including a barrel provided with a water drainage passage and further including a valvular element operated on the upper end of the barrel and so set up as to prevent any possibility of the drainage passage becoming clogged from sediment depositing on the upper end of the barrel, and with the valvular element capable of being vertically shifted for removing any sediment upon the upper end of the Serial No. 674,675.

barrel to prevent entry of sediment in the water drainage passage.

A further ob 'ect of the invention is to provide, in a manner as hereinafter referred to, a drain cock including a water drainage passage and further including means to prevent any accumulation of water in the passage when the drain cock is set up in operative relation with respect to the radiator.

A further object of the invention is to provide, in a manner as hereinafter set forth, a drain cock including a water drainage passage and means to prevent the lodging of sediment or the accumulation of water within the passage, or in other words to maintain the passage free at all times to provide for a proper drainage of the water when the drain cock is open. 1

Further objects of the invention are t provide, in a manner as hereinafter setforth, a drain cock for the purpose referred to, and which is simple in its construction and arrangement, strong, durable, thorougly eflicient and convenient in its use, readily installed with respect to a radiator without changing the latter in any particular, and inexpensiveto manufacture.

Vith the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts, as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claim hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several veiws Figure l is a fragmentary view of the radiator of a motor vehicle, as well as the instrument board of the latter and showing the adaptation therewith of a drain cock in accordance with this invention.

Figure 2 is a top plan View of the drain cock in accordance with this invention.

Figure 3 is a sectional elevation of a drain cock in accordance with this invention.

Figure 4 is a vertical sectional view through the barrel of the drain cock.

Referring to the drawings in detail, 1 denotes the radiator of a motor vehicle and 2 the instrument board of the latter.

The bottom of the radiator 1 is provided with an outlet connection 3, and communieating with said outlet connection 3 is a drain cock, in accordance with this lnvention and which indicated generally by the reference character 4, and which is secured to threaded wall of an opening, not shown,

' in contour.

formed in the bottom of the-outlet connection 3. To facilitate the connecting of the barrel 5 in position, the barrel is polygonal The upper terminus of the reduced portion 7 of the barrel 5 constitutesa valve seat 9, which is engaged by a valvular element of suitable contour for the purpose of closing the upper end of the passage 6, whereby communication is cut off between the connection 3'and said passage '6'. The valvular element is indicated atv 10, and-illustrated by way of example as of globular contour, but it is-to be understood that avalvular element of any suitable shape can be employed for closing the upper end of the water drainage passage 6.

Projecting laterally from the barrel 5, disposed at right angles with respect thereto, as well as being formed integral therewith, is an arm 11 which extends rearwardly from the radiator 1 and is provided near its free end with an oval-shaped slot 12 of substantial length. The slot 12 is positioned centrally of the arm 11 and is arrangedin alignment with the vertical axis of the barrel 5.

Formed integral with the barrel 5, at the lower end thereof, and extending rearwardly with respect to the radiator 1, as well as at a downward inclination, is a pair of spaced and opposed arms 13, 14.

Supported from the arms 13, 14, is a three-armed lever and the arms of said lever are indicated at 15, 16 and 18. The" arm 15 extends in lengthwisealignment with re spect to the arm 16 and is of less'lengt'hthan the length of the latter, and said arm 15 at its point of join'der with the arm 16i'spivotally connectedto the arms 13, 14, as-at 17. The free end of the arm 15 is provided with an'opening 15, and the free end of the arm 16 is provided with an opening '19. The arm'18 is formed integral with the arms 15 and 16 and extends at an angle with respect thereto. The arm 18 has its outer end offset, as at 20,-and formed integral with the said offset portion 20 is an upwardly disposed extension 21, having its free end provided with an opening The extension21 is positioned to ride against the outer side of the barrel5, as illustrated in dotted lines, Figure 3, when the lever is shifted. The offset portion 20, of the arm'18, constitutes a stop for arresting the upward movement of said arm 18 when the lever is shifted, due to the fact that the said offset portion 20 will abut against the arm 13.

Secured to the inner side of the offset portion 20 of the arm 18, at the outer terminus of said arm 18, through the medium of the securing device 23, is a vertically disposed valve stem 24, which has the upper end thereof provided with the valvular element 10. The lower end of the valve stem 2a is looped, as at 25, and through which extends the securing device 23, the latter be ing headed, and the connection between the looped end of the valve stem 24 and the securing device 23 is such that the lower end of the Valve stem 24 can pivot on the arm 18 when the lever is shifted to open or close the valvular element 10.

Connected with the lever is a controlling element for the valvular element '10, and which acts as a means for maintaining the valve 10 in closed position when the lever is in normal position, and which further acts as a means for maintaining said valvular element 10 in open position when the lever is shifted from normal position to provide for the opening of the passage 6, and the said controlling element will maintain the valvular element 10 in the position as shown indotted lines of Figure 3 until the lever 16 is shifted back to normal position, as illustrated in full lines, Figure 3. The said controlling element comprises a headed bar 26 which extends through the slot 12 and which has its head 27 connected with the arm 15 through the medium of the opening 15. Interposed betwcenthe head 27 and the arm 11, and surrounding the bar 26, is a coiled spring 28, and which acts to maintain the lever in theposition shown in-dotted lines in Figure 3, when the lever is shifted from inoperative position and when the lever is maintained in the position as shown in dotted lines, Figure 3, the valvular element 10 will be held off its seat, under such conditions providing-for the drainage of the radiator 1. J The lever can-be' operated from the vehicle body or from a point below the outlet connection 3. The means for operating the lever from the instrument board 2 of the vehicle consists of an elongated flexible pull member 29, having a hand grip 30 at its upper end, which is supported in the instrument board 2, and said pull-member 29 extends through a guide 31, formed integral with one side of the arm 11 and is connected at its lower end, as at 32, to the extension 21, through the medium of the opening 22. The means for operating the lever from. below the radiatorconsistsof a pull bar 33, which has one end, asat 3t,connected to the arm 16, through the medium of the opening 19.

The arranging of the valvular element 10 on the upper end of the barrel 5, prevents any accumulation of the water within the drainage passage 6, under such conditions overcoming any possibility of the passage 6 freezing up, and furthermore, the mount ing of the valvular element 10 on the upper end of the barrel will arrest any sediment or foreign matter entering the drainage passage 6, preventing clogging up of the latter. If any sediment deposits itself on the upper end of the barrel 5, it is shifted therefron'i when the valvular element is moved to open position.

The body of the drain cock may be set up 01": any noncorrosive metal, such as brass, bronze, copper, or other suitable material which will not rust, and the lever element and its connections can also be set up of such material, and as the construction is such as to prevent any possibility of the drain cock freezing or clogging up, it overcomes any possibility of inconvenience when draining, or any retardation in connection with the drainage of the radiator, and although the preferred embodiment of the invention is as described and illustrated, yet it is to be understood that changes in the details of construction can be had which will fall Within the light of the invention as claimed.

lVhat I claim is A. drain cock comprising a barrel provided with a drainage passage, a valvular element seating on one end of said barrel for opening and closing said passage, a valve stem carrying said element and extending through and projecting from said passage, a threearm lever pivotally supported from said barrel and having one of its arms pivotally connected with the projecting end of said stem, an operating means for said lever connected to one of the other arms of said lever, that arm of said lever pivotally connected with said stem provided with an extension, an operating means for said lever connected with said extension, and a controlling element connected to the remaining arm of said lever and slidably connected with said barrel and constituting means for maintaining th valvular element in open and closed position.

In testimony whereof, I affix my signature hereto.

WILLIAM B. GEORGE.
